Bug on Hisense with Subtitles

Hello,
I have a Hisense 40A4BG and I am experiencing some subtitles issues since last month. When I play a movie or tv show with subtitles on, most of the times it shows the subtitles in a strange language (like arabic), other times it shows the subtitles duplicated, other times it does not show any subtitle. I use Plex mainly to watch movies with subtitles (the movie may have other subtitles languages) and for Watch Together feature. I can get it to work after exiting and entering the movie after 3 or more attempts. It is getting out of hand… I’ve tried in LG Smart TV and no issue at all…

Thank you

Hey,

Since 3 or 4 days ago, my subtitles stopped working at all. I can select (like external or from Opensubtitels.org), but they do not appear at all?!

TV model:
Hisense 70A6BG

Any idea?

Could we get logs?
